Embodiment Construction
[0023] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0024] As a first aspect of the present invention, an outdoor unit of an air conditioner is provided. Such as Figure 1 to Figure 5 As shown, it includes a compressor 10, an external heat exchanger 20, a first connecting pipeline 30 and a first valve 40. The compressor 10 communicates with the first connecting pipeline 30 through the external heat exchanger 20, and the first valve 40 Set on the first connecting pipeline 30, the outdoor unit of the air conditioner also includes a second valve 50 for controlling the connection or disconnection of the refrigerant flow path between the heat exchanger 20 of the outdoor unit and the compressor 10, and the second valve 50 is arranged on the between the heat exchanger 20 and the compressor 10 . Since the ...

The invention provides an air-conditioning outdoor unit, an air-conditioning system and a shutdown method of the air-conditioning system. The air-conditioning outdoor unit comprises a compressor, an outdoor unit heat exchanger, a first connecting pipeline and a first valve. The compressor is communicated with the first connecting pipeline through the outdoor unit heat exchanger. The first valve is arranged on the first connecting pipeline. The air-conditioning outdoor unit further comprises a second valve which is used for controlling communication or disconnection of a refrigerant flow path between the outdoor unit heat exchanger and the compressor and arranged between the outdoor unit heat exchanger and the compressor. As the second valve is arranged between the outdoor unit heat exchanger and the compressor, when the air-conditioning system is shut down, by closing the first valve and the second valve in due time, no refrigerating fluid exists in the compressor or the amount of the remaining refrigerating fluid is small, the concentration is within the safety range, and therefore combustion or explosion accidents caused by ignition of the compressor can be avoided, and the safety of the air-conditioning outdoor unit and the air-conditioning system is further improved.
Description
technical field [0001] The present invention relates to the technical field of heat exchange systems, and more specifically, to an outdoor unit of an air conditioner, an air conditioner system and a shutdown method of the air conditioner system. Background technique [0002] When the air conditioning system in the prior art is in a shutdown state, the refrigerant is recovered on the side of the outdoor unit of the air conditioner. Since the compressor is connected to the heat exchanger of the external machine, the refrigerant is not only stored in the heat exchanger of the external machine, but also stored inside the compressor. [0003] When the refrigerant is a flammable refrigerant, if the compressor accidentally ignites due to electrical failure or other problems (for example, if the compressor has not been turned on for a long time, the motor in the compressor is aging and short-circuited, which may cause the igniting when it is turned on), and at this time the outdoor ...
